No. : XMML100401147 Date : Apr. 26, 2010 Page : 11 of 15 11 Surface Burning Characteristics I. TEST CONDUCTED This test was conducted in accordance with ASTM E84:2009c Standard Test Method for Surface Burning Characteristics of Building Materials. II. INTRODUCTION The method designated as ASTM E 84:09C. “Standard Method of Test for Surface Burning Characteristics of Building Materials” is designed to determine the relative surface burning characteristics of materials under specific test conditions. Results are expressed in terms of flame spread index (FSI) and smoke developed index (SDI) The purpose of this test method is to determine the relative burning behavior of the material by observing the flame spread along the specimen. Flame spread and smoke developed index are reported. However, there is not necessarily a relationship between these two measurements. III. TEST PROCEDURE The tunnel is preheated to 150 degrees Farenheit, as measured by the floor-embedded thermocouple located 23.25 feet downstream of the burner ports, and allowed to cool to 105 degrees Farenheit, as measured by the floor-embedded thermocouple located 13 feet from the burners. At this time the tunnel lid is raised and the test sample is placed along the ledges of the tunnel so as to form a continuous ceiling 24 feet long, 12 inches above the floor. The lid is then lowered into place. Upon ignition of the gas burners, the flame spread distance is observed and recorded every 15 seconds. Flame spread distance versus time is plotted ignoring any flame front recessions. If the area under the curve (A) is less than or equal to 97.5 min-ft, FSI = 0.515xA, if greater, FSI = 4900/(195-A). Smoke developed is determined by comparing the area under the obscuration curve for the test sample to that of inorganic reinforced cement board and red oak, arbitrarily established as 0 and 100, respectively. IV. CONDITIONING Prior to testing, the sample was conditioned to a constant weight at a temperature of 73.4+5 degrees Farenheit (23+2.8 degrees Celsius) and at a relative humidity of 50+5% *************To be continued*************

FSI SDI 5 50

RATING: The National Fire Protection Association Life Safety Code 101, Chapter 10, Section 10.2.3 “Interior Wall and Ceiling Finish Classification” has a means of classifying materials with respect to Flame Spread and Smoke Developed when tested in accordance with NFPA 255, ASTM E84, UL 723 “Method of Test of Surface Burning Characteristics of Building Materials”. International Building Code, Chapter 8, Interior Finishes, Section 803 “Wall and Ceiling Finishes”, was classified in accordance with ASTM E 84 or UL 723. Such interior finish materials shall be grouped in the following classes in accordance with their flame spread and smoke-developed indexes. **********To be continued************

TEST REPORT

No. : XMML100401147 Date : Apr. 26, 2010 No. : 13 of 15 The classifications are as follows: Class A

Class B Class C

Flame Spread Index

0-25 26-75 76-200

Smoke-developed Index

0-450 0-450 0-450

Since the tested sample received a Flame Spread Index 5 and a Smoke Developed 50, it would meet the requirement of Class A Interior Wall & Ceiling Finish Category.

Figure 2 Smoke Developed Chart WARNING: The use of supporting materials on the underside of the test specimen has the ability to lower the flame spread index from those which might be obtained if the specimen could be tested without such support. These test results do not necessarily relate to indices obtained by testing materials without such support. Testing of materials that melt, drip, or delaminate to such a degree that the continuity of the flame front is destroyed, results in low flame spread indices that do not relate directly to indices obtained by testing materials that remain in place. The test results relate only to the specimens of the product in the form in which were tested. Small differences in the composition or thickness of the product may significantly affect the performance during the test and may therefore invalidate the test results. Care should be taken to ensure that any product, which is supplied or used, is fully represented by the specimens, which were tested. The specimen was supplied by the sponsor and SGS-CSTC ANJI Branch was not involved in any selection or sampling procedure. Note: The test was carried out by a SGS laboratory. ************To be continued***********
